Think integration and remember the principles of the past

The past masters combined parameters such as aesthetics, durability, user-friendliness and environmentalism. NIRAS is rethinking the classical principles and combining them with current technology and design.

One can certainly achieve a good indoor climate in buildings without air-conditioning. In architectural terms this is liberating as it means space will not be required for air-conditioners and disfiguring ventilation shafts.

Nature’s Indoor Climate is based on experience with integrated, natural indoor-climate solutions. Many of them are a re-discovery of principles that are over 200 years old.

• Chimneys renew the air, the Rastrelli principle
• More than a window, the Fortochka principle
• The open walls, the Palladio principle
• Trees and running water, the Dagmar principle
• Screening off the wind, the Aiolos principle
• Screening out the sun, the Matisse principle
• On-the-spot extraction and ventilation, the Texas principle
